To all whom it may concern: 7

Be it known that I, WILLIAM A. HULSE, a' citizen of the United States,residing at Rochester, in'thecounty of Monroe and State of New York,have invented certain new and useful Improvements in Methods of andMechanism for Making Tobacco Cigarettes, (for which the followingLetters Patent have been granted, viz: Great Britain,No. 12,736, datedJuly 11, 1892; Dominion of Canada, No. 39,191, dated June 24, 1892; NewSouth lVales, No. 3,771, dated May 2, 1892; Victoria, No. 9,675, datedMay 26, 1892, and Spain, No. 13,505, dated August 8, 1892,) of which thefollowing is a specification, reference being had to the drawingsaccompanying and forming a part of the same. I The present inventionrelates to improvements in the method and mechanism by which acontinuous Web or strip of paperiswrapped around a tobacco-filler andits opposite edges united to produce a continuous or longcigarette'cylinder composed of a tobacco filler inclosed in a paperWrapper, which is to be cut upinto suitablelengths for marketablecigarettes.

Heretofore such cigarettes have been made, as by the Bonsackmachinedescribed and shown in United States Letters Patent No. 247,795, datedOctober 4, 1881, by feeding a rod or filler of tobacco and a continuousstrip of paper simultaneously through a tubular construction in whichthe paper strip is wrapped around the tobacco, the edges of the stripbeing brought together and overlapped and secured by means of pasteapplied'to the overlapping edges. There is also de-. scribed in UnitedStates Letters Patent No. 437,207, dated September 30, 1890, devices forforming continuous cigarettes by which a continuous strip of paper iswrapped around a tobacco filler and its opposite edges are brought intocontact with each other in an outstanding position, so that pressuredevices can operate upon the opposite sides of such edges and outside ofthe wrapper to -incorporate the edges together and form an outstandingseam, preferably without the application of adhesive material. Suchcigarettes are objectionable, as the outstanding seam is peculiarlyexposed to abrasion and is liable to become crumpled and loosened, andthe cigarettes fail'to smoke properly or at all.

It is the object of my improvements to provide a method and mechanism bywhich long or continuous cigarette-cylinders, composed of a tobaccofillerinclosed in a paper wrapper having a longitudinal seam formedwithout the application of paste or other adhesive material and laiddown flat upon the body of the cigarette-cylinder, are produced bycontinuously wrapping the paper strip around the filler andprogressively bringing and sealing the opposite edges together into alongitudinal seam, which is laid or flattened down to coincide with thebody of the finished cigarette. V

For a clear understanding of my invention a detailed description ofmechanism of the preferred form for carrying out'my improved method isillustrated in the accompanying drawings, the construction shown andhereina'fter'specifically described being such that it can be easilyapplied to cigarette-machines now in practical use-as, for instance, tothe Bonsack machine above referred toby taking off the Bonsackwrapping-tube designated by G in Figure 1 of the drawings of the saidBonsack patent and substituting therefor my mechanism without changingmaterially the other parts of the Bonsacl: machine. It follows,therefore, that the mechanism shown and described in the said Bonsackpatent for preparing the tobacco, for forming the same into a rod orfiller, and delivering it upon the wrapping-strip as the strip entersthe wrapping-tube, as well as the mechanismfordelivering the completedcigarette-cylinder to the cutting devices and cutting it into cigarettelengths, or any other well-known forms of mechanism or devices forperforming these several operations may be employed in connection withmy improvements.

In the drawings, Fig. 1 represents a view in perspective of such partsof a cigarettemachine as are necessary to illustrate the application ofmy improvements thereto. Fig. 2 represents a longitudinal section of thesame between the lines or and 1/ of Fig. 1. Figs. 3, 4, 5, 6, and 7represent cross-sectional views on the lines 1, 2, 3, 4, and 5,respectively, of Fig. 53, showing the position of the various parts atthose points as the wrappingstrip and the tobacco filler depositedthereon are advancing. Fig. 8 is a section of a modified constructionthrough the line 5 of Fig. 2. Fig. 9 is a view in perspective of thedevice for folding or coiling the edges of the wrapper-strip. Fig. 10 isa section of a finished cigarette shown in perspective. Figs. 11 to 17of Sheet 2 of the drawings show modifications of the construction shownin Figs. 1 to 9, inclusive, Figs. 11 and 12 being longitudinal sectionaland plan views of a filler-compressing and paper-wrapping tube providedwith my improvements; Fig. 13, an enlarged longitudinal sectional viewof the part included between lines .2 .2 of Fig. 12; and Figs. 14, 15,16, and 17 being cross-sections on the lines 6, 7, 8, and 9,respectively, of Figs. 12 and 13.

By reference to the figures of the drawings, A represents a tube throughwhich the tobacco filler and the paper-wrapping strip 13 are advanced orfed, and by means of which, together with certain attachmentshereinafter described, the paper strip is gradually brought from a fiatinto a tubular shape to encircle or surround the tobacco filler. Thistube is shown as attached to a cigarette-machine by any convenientmeans, as by support A and frame 0 secured to frame 0' of the machine.The tube is conveniently made by forming two nearly semicircular parts,the lower part being designated by O and the upperpart by D, from sheetmetal and uniting them into a tube adapted to form a channel orpassageway B, through which a tobacco filler and a wrapping-strip areadvanced simultaneously, the wrapping-strip being gradually brought froma flat into a tubular form to completely encircle or surround thetobacco filler.

The parts 0 and D are secured together by means of solder or brazing orconnecting bands or pieces in such manner as to leave slits or openingsa a between the parts G and D,through which the edges of thewrappingstrip and endless band E can project. The lower part 0 projectsrearwardly beyond the part D and gradually recedes from asemicylindrical into nearly a flat shape, and its edges are folded overto form guides b b for the edges of the paper strip, these guidespreferably extending somewhat beyond the junction of the part G and D toor near the beginning of the slits a a. The rear end of the part O isprovided with a friction-roller F, over which the paper strip and theband E pass. This roller is journaled in side pieces 0, secured to theedges of the part 0, and on the upper face of which is a passage-way forthe paper strip 13 and upon its under face a similar way for the band E.After passing over the roller F the band E passes underneath the part 0till it reaches an opening ll, cut through the wall of part 0, where itenters the tube A. The paper strip passes over the roller F above theband E and enters the rear end of the part C, its edges lying in theguides I) l), and as it is advanced it is gradually brought intosemicircular shape as it enters the mouth of the tube, and is therebrought in contact with the upper surface of the band E. The band Epasses through the tube and over a pulley I, located beyond the forwardend of the tube and journaled in attachments to the frame of the machineconveniently, as shown in the drawings of the said Bonsack patent, andoperates to advance or draw the paper strip and the tobacco fillerdeposited thereon through the tube and beyond its forward end, ifdesired.

The parts 0 and D are preferably tapered, so as to form a tapered orgradually-contracted space or channel 13 for the purpose ofcompressing'the tobacco filler to such degree that as it passes out fromthe forward end of the part D and the pressure is released therefrom itwill expand sufficiently to fill the sealed wrapper. The part 0preferably extends beyond the forward end of the part D and ispreferably formed into a tube .1, through which the band E and thecigarettecylinder are passed.

As the strip of paper carrying the tobacco is advanced through the tubeA by means of the continuous movement of the band IE, it is graduallyWrapped or folded into tubular shape, and its opposite edges, havingpassed out through the slits ct a with the edges of the band, aregradually brought toward and into engagement with each other upon theouter surface of the part I) and are secured together to form a seamlaid down flat upon the body of the wrapper without the application ofpaste or other adhesive material.

In the drawings, K is a projection secured to the uppersurfaee of thetube, and on either side thereof are secured at their upper edges thinmetal strips d (1 whose lower edges and forward ends are free orunsecured. The inner and under surfaces of these strips conformsubstantially to the upright surfaces of the projection K and the uppersurface of the part D, but the strips are so arranged relatively tothese surfaces that narrow guideways are formed for the edges of thepaper strip and the band E. These strips are preferably slightly elasticat their lower edges and foward ends, and are arranged to hold the edgesof the band and the paper strip in close contact with the surface of thepart 1). The portion of the projection K between the strips (Z d isthinned away till it terminates in a knife-edge, which permits the edgesof the paper strip to come in contact with each other, as shown insection in Fig. at of the drawings. The edges of the paper strip beingnew in contact with each other enter a device L, secured to theprojection K, in which they are gradually folded or rolled upon eachother to give the necessary number of thicl nesses of paper for theseam.

The device L is conveniently made by bonding two strips 6 e of thinmetal spirally and securing their rear ends to a supportingblock orpiece M, in which they are contained so as to form a narrow channelbetween the strips for the passage of the paper edges. As the paperpasses through this channel the edges are folded or coiled to such anextent that when they emerge into the small tapered chamberfthe coilingwill be continued according to the length and taper of the chamber. Theexit from this chamber should be small enough to consolidate the severalthicknesses or folds of paper into a compass to give a seam of thedesired size.

The piece M is preferably made separate from the projection K and isremovably secured thereto by inserting it into dovetailed or.othernotches cut through the projection, the upper edge of thepiece M beingcorrespondingly notched to prevent any longitudinal movement. The pieceM is shown in perspective in Fig. 9 of the drawings.

The engaged edges of the wrapper as they emerge from the mouth of thetapered chamberf pass directlynto a pressure device in which they aresecured together to form a seam without the application of paste, andthis seam is pressed down flat, so as to conform to the body contour ofthe finished cigarette, as seen in Fig. 10 of the drawings.

The pressure device is composed of two main operative parts, one parthaving a wheel N journaled in a plate N arranged to slide in suitableways in a frame Osecured to the main frame 0 of the machine and drivenby a pulley P, as seen in Fig. 1, which pulley is in turn driven by across-belt P, which passes over a positively-driven pulley I, over whichthe bandE passes and by which it is driven, as seen in Figs. 11 and 12,the size and arrangement of the parts being such that the periphery ofwheel N is caused to travel at the same speed as the band E, andconsequently the paper strip B is advanced through the pressure deviceat the same speed with the periphery of the wheel N, which bears uponits engaged edges. The pulleyI is driven by a beveled gear R attached toits shaft which meshes with a corresponding gear, as shown in Fig. 1 ofthe drawings of the said Bonsack patent hereiubefore referred to.

The second part of the pressure device, as shown in Figs. 1 to7 of thedrawings,'is a small roller Q, journaled in the Walls ofa recess formedin the upper surface of the part D. The shaft of this roller is arrangedat right angles to the line of the advance of the wrapper and filler,and the face of the roller is directly in the path of the folded edgesof the wrapper, so that such edges will pass over the face of the rollerand the roller is revolved by the friction or pressure of the opposingparts. The periphery of the wheel N is 7 arranged to bear directly overthe face of the roller Q, and this wheel is preferably adj ustable bymeans of a screw g, passing through the top of the frame 0 and connectedwith a spring h in such manner that the piece N, carrying the wheel Nand the pulley P, can be moved up and down to bring the desired pressureupon the seam, the spring h operating to compensate for any variationsin the thickness of the seam. The periphery of the wheel N is serratedor roughened in any desired manner, so that as it is forced down uponthe engaged edges of the wrapper and the pressure is resisted by thesurface of the rollerQ, located within the wrapper and operating as ananvil to resist the pressure of of the wheel N, the engaged edges of thewrapper will be pressed into close contact and will be indented andincorporated or embodied into each other sufficiently to form a strongand reliable seam without the application of paste or other adhesivematerial to hold the tobacco filler in place and to resist any pressurewhich may result from the expansion of the filler when released frompressure.

To facilitate the incorporation of the engaged edges of thewrapping-strip into a seam, the roller Q may be provided with notches orserrations, which should be arranged to match those upon the peripheryof the wheel N, as shown in Fig. 2, and the roller Q is preferablyseparated from the tobacco filler bya wall or partition q, so as toprevent the roller, from interfering with the passage of the filler andto-prevent the fibers of tobacco from interfering with the operation ofthe roller.

The position of the parts when the wrapper edges are pressed together toform the flat seam is shown in Fig. 7, in which it is seen that theadvancing tobacco filler is encircled or surrounded by the advancingwrapper, and that one of the pressure devices, the wheel N, is locatedoutside of the wrapper to give the necessary pressure, while the otherpart, the roller Q, is located within the wrapper to resist thepressure-of the wheel N, and that the engaged wrapper edges pass betweenthe pressure-producing and pressure resisting parts and are incorporatedinto a finished seam, which is flattened down uponthe body of thewrapper. It is also seen that at this point and when the engaged edgesof the wrapper are being incorporated into a seam and forced down uponthe body of the wrapper the tobacco tiller occupies a chamber Which isencircled by the wrapper, which chamber is shown in the drawings as thepart of the channel B not occupied by the wrapper and belt.

It is observed that instead of the roller Q the smooth plain surface ofthe part D may be used for the anvil or resisting part of the pressuredevice, as shown in Fig. 8 of the drawings, and that in suchconstruction no enlargement of the part D would be required to seat theroller Q. The roller, however, as

IlO

it moves under pressure with equal speed with the wheel N, greatlyreduces the liability of tearing the paper as it is advanced.

The tobacco filler, as it passes through the contracted part of thechannel B beneath the part D, in which the roller Q is located, will besufiiciently compressed, so that when it passes from under the forwardend of the part D and is thus released from pressure it will immediatelyexpand to fill the now sealed wrapper and produce a smooth cigarette.The diameter of the roller Q can be made very small as compared with thediameter of the channel B at this point, and consequently but littleexpansion of the filler will be required to take up the slack of thewrapper.

It is here observed that the capacity of fibrous tobacco to expand afterit has been compressed depends largely upon the length of time it isretained under pressure. If retained under pressure only momentarily, itwill expand to nearly its original bulk. In a machine of theabove-described type, which easily makes two hundred cigarettes perminute, the tobacco is retained under pressure during only the fractionof a second, and even if the cross-area of the filler-chamber at thepoint where the pressure devices operate to form the finished seam isconsiderably less than that of the whole interior of the wrapper thetobacco will quickly expand when the pressure is removed and will takeup the slack and completely fill the wrapper.

\Vhen the completed cigarette-cylinder has passed beyond the end of tubeA, it may be delivered to a cutter and severed into smokable lengths bythe mechanism set forth in the said Bonsack patent or by any otherwellknown means.

In the mechanism heretofore specifically described and shown in Figs. 1to 9, inclusive, of the drawings the edges of the wrappingstrip areturned outward and rolled over outside of the body of the wrapper andthe seam is compressed down on the outside of the wrapper. By slightchanges ormodifications in the construction the wrapper edges are turnedinwardly and the seam is formed within the wrapper and is pressedagainst its interior surface.

Figs. 11 to 17, inclusive, of Sheet 2 of the drawings representsubstantially the same construction as heretofore particularlydescribed, with the exception of devices for turning the edges of thewrappingstrip B inwardly relative to the body of the wrapper and formingthe seam on the interior thereof, and consequently it is considerednecessary to describe only these devices. In these figures of thedrawingsJ is a longitudinal groove or depression formed on the uppersurface of the partD of the tube A. jj are strips of thin metalconforming to the upper surface of the tube and secured thereto at theirrear ends, their forward ends being left free or unattached. The upperedges of these strips at their forward ends are turned downward into thegroove 2', and the strips are preferably so constructed that theirforward ends will press downward upon the surface of the tube, but willeasily spring upward and outward to permit the passage of the edges ofthe paper strip and the band E between them and the surface of the tube,as seen in Fig. 14. The function of these strips is to guide the edgesof the paper and turn them downward into the groove 1' as the strip isadvanced through and along the tube and as the edges are turned downwardto prevent the body of the strip from crumpling or wrinkling. After theedges of the paper strip have passed the forward ends of the strips j jthey are advanced to the downward projections m, secured to the part C,as shown in Fig. 15, and are still further turned downward toward thecenter of the tube, and as they pass the last of these projections theyare brought in contact and pass into a slit 0, opening into a guidewayformed on the top of the tube, in which is located a strip of metal a,curved around a small core 19, secured to the wall of the guideway, bywhich the downwardly-projecting edges of the strip are gradually rolledor coiled upon each other and partly around the core 1), as shown inFigs. 13 and 16. The free end of this core is tapered and projects intoa tapered chamher 7", whose exit is near the pressure-Wheel Q, and asthe partly-coiled edges are advanced along the tapered end of the coreand to the exit of the chamber they are still further rolled or coiledtogether to produce the desired number of thicknesses of paper for theseam, as shown in Fig. 17, and are delivered to the pressure device.

The construction of devices by which the wrapper edges are turneddownwardly or inwardly and folded or rolled together and the seam formedand secured upon the inside of the wrapper is more specificallydescribed and is claimed in an application filed by me March 21,1893,and serially numbered 167,032.

As I am, so far as I am aware, the first to devise a method to produce acontinuous or long cigarette having a longitudinal wrapperseam formed byfolding, rolling, or interlocking the opposite edges of thewrapper-strip together and laid down upon the body of the cigarette anda form of mechanism by which such method can be practiced I do not wishto limit my invention to any special means or mechanism for forming theloose tobacco into a filler or rod, or for advancing or feeding thetobacco filler and wrapper-strip to a seamforming mechanism, or to anyspecial devices for wrapping the strip of paper around the filler, orfor bringing the opposite edges of the wrapper-strip into engagementwith each other to form the necessary thicknesses of paper for the seam,as all these operations are old and can be carried out by a greatvariety of well-known devices or mechanisms.

The novelty of my invention relates more particularly to the step oroperation by which the opposite wrapper-edges, after they have beenfolded, rolled, or otherwise interlocked together, are secured into acompleted seam at a point where the wrapper surrounds or encircles thefiller and while the filler and wrapper are being simultaneouslyadvanced, and especially to the application of pressing, crimping, orindenting devices arranged to operate upon the opposite sides oftherolled or folded-together wrapper edges to incorporate them'into acompleted seam.
